T all 'ui/0m it may conne/"n Be it known that we, *Vinnie rr llTnocLAw- .sin und'MionAnr.

`he nniin objects of this invention are to provide en improved form oi' draft gear for railway cnrs, und the likeT equipped with shock absorbing ineens; to provide en iinproved eonntruction und urrungemcnt of the shock absorbing meu-nn und the connections thereof to the cui' coupler; to provide improved ineens for ('onneeting;` together the shock :iheorhing means nl" opposite ends oi' the cur so es lo multiplyv the elim-,live renst ence und appli' it to beet udvuntlrgfe; und to proridc un improved comlrlution of the fuirL pori ing member@l und improved niounlin ol vlille draft gear perl thereon7 so un to pernin the end sill ol the cur to he removed withA out dismantling' the entire gear.

An illustrative embodiment of this invenlion is shown in the eCcoin]ninyingJ drnwings. .in which l 1ifigfure 1 is a. side elevation of e draft ur constructed accordingto this invention. hier, Q'is ai. plan View of the suine. parte tlwref'ylibeing broken :iwny to more clearly illuelrute the construction.

ln the construction Shown in the drnwingr5 the supporting' element for' the draft geur comprises members l and Q, preferably adje.- cent the sills, in the forni of -beems en tending longitudinally of the cer and forniing' a part of the construction thereof and providing guide'ways for the Shook absorbing,r device. A spacer block 3 is secured between the I-benms l and 2 by nie-.ins of e pin 4. A' druivhur 5 is slidfihlymounted between the Iben1ns l end 2 et their outer ends and carries acer coupler 6. A Shock absorbing device is Vinterpo.'-:ed between the spec-er block 3 and the drawbur 5 for enel ,ioning the thrust. This Shock absorbing de.- vice comprises bloeksf?, 8 and' 9 slidebly mounted between theI-.beems 1 Aand 2 and spaced apart by interposed springs l() and ll. The blocks l and 9 ure rcepectively provided with studv l2 :1nd l2', litting in .sockets in the spacer block 3 and lruwhur Si, and being of suillcient length to prevent the disengagement of the blocligsl 7 and 9 respectively from the block 23 or druugbur 5 during any relative movement thereof.

The slides ,13 et oppoedle mul.` olf the our ure connertml together hv nenn ol' rods Il? so that when the drnxzhur ."3 ol one geur pulled outwardly, boih sein. ol' springs in the oppoeiie gear, und the rein #et of .springs in Seid one geur ere brought under empression :is will hcreirnifte- :ippeur in deserihing the operation. '.lhe rode 25 hure squure hands l which .--re :wird in Snelgids i2? :ind Secured against dieengnigomont therefrom by .ineansol pins 28. 'The :anchois Si? ure longer than the, heu'dS 26.y .so es to allow :i relative movement of the slides und rod` in euse the llO drawbar is pushed inwardly. The rods are also rovided with turnbuekles 25A by means ofp which they may be adjusted to take up slack.

The end sections 29 of the I-beams 1 and 2 are removably att-ached so that they may be disconnected from the I-beams, and-fthe drawbar 5 removed by' withdravvinp,r the key 19,50 as to permit the replacing ofthe end sill 8O of the car without damage to the end sheathing.

The operation of the device shown is as followsi Normally, the parts arel'in'the position shown in Fig. 2, so that with respect to the I-beams l and 2 the key 21 is free to move only in the direction toward the right of the tig-ure, thel key 20 being free to move in the 'direction' 4toward the left, and the key 19 being` free to move in' either direction. When the drawbar 5 isy pushed inwardly, the keys 19 and 520 are urged inwardly, thereby causing a movement of the blocks .to which they are connected toward the key 19 transmits the pull to the slides 13 of the respective draft gear, and through the blocks 9 and 16, which' are held Stationary by the key S21, thereby resulting in a compression of the springs 10, 11, 17, and 18. During' this action of the shock absorbing device, the slides remain stationary by virtue of the arrangement of the slots 2li. When there is a pull on the drawbar 5, the

tension rods 25 to the slides on the draft gear at the opposite end of the car, which latter slides Acause the compression of the springs of the respective vdraft gear in a similar manner as when the springs are compressed by reason of a' thrust on the draw-bar of said respective draft gear; During the movement of the lslides 13, the key 20 is held against movement therewith, and veliects the compressionmi the springs 11 and 1 8 through the movement of the key 21 toward'the key 20. Thus, to a thrust on the drawbar 5, six springs are brought into y ietion` to resist the strain, Vand whentliere i a' pull on the drawbar, nine springs are jbrought into action tovresist the strain. Although but one specific embodiment of this invention is herein shown and described, it will be understood that numerous details of the construction shown may be altered or omitted without departing` from the spirit of this invention, as defined by the following claims.

transversely alined sets and spaced apartv longitudinally, resilient means interposed between the blocks in 'each longitudinal row,

' a drawbar, keys connecting some of the blocks in transverse rows and slidably supporting said blocks and slides on said members, said slides and members being slotted to receive said keys, said slots being arranged so as to permit the compression of all of said resilient means when said drawbar is pushed inwardly, and to permit the compression of one set of said springs when said drawbar is pulled outwardly.

2. A draft gear comprisunglr a pair of members spaced apart, a hollowslide supportedl at the outside of each of said members, a plurality of blocks slidably mounted between said members and in said slides, said blocks being arranged in substantially transversely alined sets and spaced apart Alongitudinally, resilient means 'interposed between the blocks vin each longitudinal row, a drawbar, keys connecting some of the blocks in transverse rows and slidably supporting said blocks-and slides on said members, said members being slotted to permit the forward key to be relatively moved therein in both directions, and the rearward and middie keys to be relatively moved therein only in relatively opposite directions, and said slides being slotted to permit said forward. and rearward keysto be relatively moved therein only in relatively opposite directions, and permit said middle key to be relatively moved therein in both directions for the purpose specified.
